Notion Snap show squares instead fonts

I’ve installed notion via snapcraft on Manjaro 21.1.6 Gnome and snap 2.51. It works fine but doesn’t show the fonts when open the pop up for saving something or browse for open a document. I’ve tested cleaning the fonts cache as seen in other topic but noting works. Here is an screen shot of the problem:

This bug affects many apps: Teams, Slack, VSCodium etc. It is probably a bad integration of snap with electron apps. Removing the font cache doesn’t work.
